How to Write a Sample letter

This is the letter to convey my apology after break up of love. First of all I should regret for my behaviour and I regret for it in a very precise manner. Am here to say sorry for my actions that I have did for you and which made you to break up my love. The reason for my behaviour is only my anger and nothing else. There is no intention to throw you away or anything else. I don’t think that the word sorry will re-fix us. But since I hope you will re-consider me one more time to give me a chance to enter to your life am saying this, am sorry, am terribly sorry. I need you to excuse me for one last time and you will never face this again. I promise you.
